it appertains to make and use the saine.

My invention relates to metallic barrels, and the object of my invention is to produce a Vmetal barrel, which shall be light, strong,

of a bilged forin and which shall be so constructed that rthe head can be readily removed Where access to the interior-is desired.

A further object of my invention is't'o provide a barrel .which can b'e readily knocked downwhen the barrel is to be reshipped for re-useas a container.

This present application for United States Letters Patent relates only to the construction of the staves and hoops .of my improved barrel.

Another application for United States Letters Patent, Serial No. 57,190 is filed herewith covering the head. and chine ring for use with my-improved barrel.

In the drawings Figure 1, is a perspective view of my improved barrel; Fig. 2, is a partial longitudinal section of' my improved barrel along the line 2 2 of Fig. 1;

Fig. 3, is a transverse section along the line 3 3 of Fig. 1,;

-' Fig. 4, is a perspective View of one stave;

Fig. 5, is a perspective view of one head;

Fig. -6, is a perspective view of the chine ring showing the ends thereof separated and Fig. 7, is a top plan view ofthe juncture of two staves.

In the drawings, 10,' represents a. stave of which there may be any approved number used in the barrel, there being eight barrels shown.- Each stave on its outer surface is provided with a plurality of corrugation's 11 I Specification of Letters Patent. Patnte'd Sept. 11, 191,7u

insu-re an approximate smooth surface the barrel to roll upon.

The corrugationsll 'do'not extend across the full width of the staves but smooth borders 12--12 are provided between the ends of said corrugations andthe edges of said staves.

Each sta-ve along one edge is provided with a. rib 13 projecting radially inward, and the inner edge of said rib issub'stantially straight as shown at 14 in Fig. 4.

On the other edge of each stave is provided a rib portion 15, which projects radially inward and has formed integrally on its inner edge, a curved, flange 16,'the flange 16 is substantially straight longitudinally,

but its outer edgeis curved as shown.

The-rib 18 and the rib formed of the straight portions 15 and 16 are of the same length and extend between the inner surfaces ofthe heads 18 as shown in Fig. 2.-

for

The edge 14 and the portion 16 are formed i substantially straight longitudinally so as to give said ribs a greater radial width at the largest part of the bilge of the barrel than said ribs have at the ends.A By this means` said ribs are made very much stronger and the barrel 1s rendered more able to resist stresses applied to the bilge thereof. The

` lindrical surface 20 of the ange 21 ofthe head 22 shown in Fig. 5.

The portions 19 extend as at 23-24 beyondthe rib 13 and the rib formed by the portions 15 and 16. On the outer ends of the portion 19, the flange 25 is bent over as .shown in Fig. 4. The flange 25 is of a length circumferentially about equal to three-quarters of the circumferential distance between the outer surface of the rib 13 and the outer surface of the portion 15. A tab suoli as 2G is provided on the portion 19 adjacent to the Harige 2 5.

.'.lhe (hinges 25 on both ends of the stave are siinilarand similarly situated, but the tabs 2G are placed diagonally Opposite on the ends of the stave as shown in Fig. 4.

The head 22 'of my improved barrel is formed with the cruciforln strengthening irib 27 having depressions 28 between the arms thereof. and a circular strengthening rib 29 connectingsaid arms.` The fiat annnlar portion 30 extends radially outward from the strengthening rib 29 to the cylindrical flange l The cylindrical surface of the flange 21 is cut in a plurality ot' places as at 31-32 and the portions snclras 33 between the ents suoli as are bent inwardly to form an acute angle with the outer cylindrical` surface 2l as is shown in Fig.v 5. e

T he circumferential length of theportion 33 is slightly greater than the circunifei.A ential length ot' the flange 25 of the slaveA permit the passage therethrough ol tabs 2G. i

One end of the chine ring is enlarged as at 37 and provided lwith a hole 38 in the outside flange for the reception of the tab 39 formed on the outside flange of the other endy ot' said 'ring'. The inside lange of said last inlined end is also provided with the tab Li() and a hole not shown is provided in the first nanied end olf said chine ring for theV reception ot the tab etO. rl`he tabs 39 and a0 are placed through the holes inithe other ends of the ring and then backwardly as shown at el in Fig. 1, thus'securing the endsl of the ring together. Hoops such as 4Q are provided for securing the staves together. rlhe process of assembling my improved barrel is as follows The rib 13 ot' one stave is introduced into the opening between the portions 15 and 1.6 of the llange rib of the next adjacent stave and the prooess is repeatedvivith additional staves uiitilthe sufficient number of staves have been tliiis assembled to form the body portion ot' the barrel.

During the process of joining the ribs together, it is evident that the ribs 13 must lie passed between the portions 24H24, and that'the portions 23 will overlie the portions 2li, hence, it is evident that the portionsl 2l bearing against the ends ot the rib 13 will prevent longitudinal displacement of one stavewitli reference to another and the portion bearing against the' portion 24 will :give additional sti'angth nat the chine of the barrel, alter the ribs of the staves are joined toget'v er as just described.

ll`he hoops il?, are driven over the body of the barrel until they lit tightly around -the bilged portion thereof. then the edges ot said hoops are swaged into the corrugations ll as at .43, thus pre'venting the hoops troni lieeoniing loose.

The head 2;). is introduced with the portions such as 3G between the portions suoli as on the ends of the stave. The head is then driven inwardly until ils inner surface rests against the ribspl and portions l5. The head is then to be turned slightly to bring portions 36 under the U shaped porlion in order to loek the head willi the staves.

The chine ring is then driven over the bilged body portions, ribs along the edges ot' said bilged body portions,`and curved ends on said staves, each of said ends having side extensions to fit over the ends of one rib ot' an adjacent stave.

l'ii testimony whereof, I aliix my signature.
